53145c2e35 Revert "HID: magicmouse: Set multi-touch keybits for Magic Mouse"
Setting these bits causes libinput to fail to initialize the device;
setting BTN_TOUCH and BTN_TOOL_FINGER causes it to treat the mouse as a
touchpad, and it then refuses to continue when it discovers ABS_X is not
set.

This breaks all known Wayland compositors, as well as Xorg when the
libinput driver is being used.

This reverts commit f4b65b9563.

0ca4cd7bcc HID: let generic driver yield control iff specific driver has been enabled
There are many situations where generic HID driver provides some basic level
of support for certain device, but later this support (usually by implementing
vendor-specific extensions of HID protocol) is extended and the support moved
over to a separate (usually per-vendor) specific driver.

This might bring a rather unpleasant suprise for users, as all of a sudden
there is a new config option they have to enable in order to get any support
for their device whatsoever, although previous kernel versions provided basic
support through the generic driver. Which is rightfully seen as a regression.

Fix this by including the entry for a particular device in
hid_have_special_driver[] iff the specific config option has been specified,
and let generic driver handle the device otherwise.
Also make the behavior of hid_scan_report() (where the same decision is being
taken on a per-report level) consistent.

While at it, reshuffle the hid_have_special_driver[] a bit to restore the
alphabetical ordering (first order by config option, and within those
sections order by VID).

This is considered a short-term solution, before generic way of giving
precedence to special drivers and falling back to generic driver is
figured out.

While at it, fixup a missing entry for GFRM driver; thanks to Hans de Geode for
spotting this (and for discovering a few issues in the conversion).

94116f8126 ACPI: Switch to use generic guid_t in acpi_evaluate_dsm()
acpi_evaluate_dsm() and friends take a pointer to a raw buffer of 16
bytes. Instead we convert them to use guid_t type. At the same time we
convert current users.

acpi_str_to_uuid() becomes useless after the conversion and it's safe to
get rid of it.

f3d3eab667 HID: i2c: Call acpi_device_fix_up_power for ACPI-enumerated devices
For ACPI devices which do not have a _PSC method, the ACPI subsys cannot
query their initial state at boot, so these devices are assumed to have
been put in D0 by the BIOS, but for touchscreens that is not always true.

This commit adds a call to acpi_device_fix_up_power to explicitly put
devices without a _PSC method into D0 state (for devices with a _PSC
method it is a nop). Note we only need to do this on probe, after a
resume the ACPI subsys knows the device is in D3 and will properly
put it in D0.

This fixes the SIS0817 i2c-hid touchscreen on a Peaq C1010 2-in-1
device failing to probe with a "hid_descr_cmd failed" error.

f4b65b9563 HID: magicmouse: Set multi-touch keybits for Magic Mouse
The driver emits multi-touch events for Magic Trackpad as well as Magic
Mouse, but it does not set keybits that are related to multi-touch event
for Magic Mouse; so set these keybits.

The keybits that are not set cause trouble because user programs often
probe these keybits for self-configuration and thus they cannot operate
properly if the keybits are not set.

One of such troubles is that libevdev will not be able to emit correct
touch count, causing gestures library failed to do fling stop.

2ac97f0f66 HID: wacom: Have wacom_tpc_irq guard against possible NULL dereference
The following Smatch complaint was generated in response to commit
2a6cdbd ("HID: wacom: Introduce new 'touch_input' device"):

    drivers/hid/wacom_wac.c:1586 wacom_tpc_irq()
             error: we previously assumed 'wacom->touch_input' could be null (see line 1577)

The 'touch_input' and 'pen_input' variables point to the 'struct input_dev'
used for relaying touch and pen events to userspace, respectively. If a
device does not have a touch interface or pen interface, the associated
input variable is NULL. The 'wacom_tpc_irq()' function is responsible for
forwarding input reports to a more-specific IRQ handler function. An
unknown report could theoretically be mistaken as e.g. a touch report
on a device which does not have a touch interface. This can be prevented
by only calling the pen/touch functions are called when the pen/touch
pointers are valid.

6f107fab8f HID: wacom: Override incorrect logical maximum contact identifier
It apears that devices designed around Wacom's G11 chipset (e.g. Lenovo
ThinkPad Yoga 260, Lenovo ThinkPad X1 Yoga, Dell XPS 12 9250, Dell Venue
8 Pro 5855, etc.) suffer from a common issue in their HID descriptors.
The logical maximum is not updated for the "Contact Identifier" usage,
leaving it as just "1" despite these devices being capable of tracking
far more touches.

Commit 60a2218698 began ignoring usages with out-of-range values,
causing problems for devices based on this chipset. Touches after
the first will have an out-of-range Contact Identifier, and ignoring
that usage will cause the kernel to incorrectly slot each finger's
events (along with all the knock-on userspace effects that entails).

This commit checks for these buggy descriptors and updates the maximum
where required. Prior chipsets have used "255" as the maximum (and the
G11, at least, doesn't seem to actually use IDs outside the range of
1..CONTACTMAX) so continue using this value.

286f3f4787 HID: wacom: Treat HID_DG_TOOLSERIALNUMBER as unsigned
Because HID_DG_TOOLSERIALNUMBER doesn't first cast the value recieved from HID
to an unsigned type, sign-extension rules can cause the value of
wacom_wac->serial[0] to inadvertently wind up with all 32 of its highest bits
set if the highest bit of "value" was set.

This can cause problems for Tablet PC devices which use AES sensors and the
xf86-input-wacom userspace driver. It is not uncommon for AES sensors to send a
serial number of '0' while the pen is entering or leaving proximity. The
xf86-input-wacom driver ignores events with a serial number of '0' since it
cannot match them up to an in-use tool.  To ensure the xf86-input-wacom driver
does not ignore the final out-of-proximity event, the kernel does not send
MSC_SERIAL events when the value of wacom_wac->serial[0] is '0'. If the highest
bit of HID_DG_TOOLSERIALNUMBER is set by an in-prox pen which later leaves
proximity and sends a '0' for HID_DG_TOOLSERIALNUMBER, then only the lowest 32
bits of wacom_wac->serial[0] are actually cleared, causing the kernel to send
an MSC_SERIAL event. Since the 'input_event' function takes an 'int' as
argument, only those lowest (now-cleared) 32 bits of wacom_wac->serial[0] are
sent to userspace, causing xf86-input-wacom to ignore the event. If the event
was the final out-of-prox event, then xf86-input-wacom may remain in a state
where it believes the pen is in proximity and refuses to allow other devices
under its control (e.g. the touchscreen) to move the cursor.

It should be noted that EMR devices and devices which use both the
HID_DG_TOOLSERIALNUMBER and WACOM_HID_WD_SERIALHI usages (in that order) would
be immune to this issue. It appears only AES devices are affected.

af22a610bc HID: asus: support backlight on USB keyboards
The latest USB keyboards shipped on several ASUS laptop models
(including ROG laptop models such as GL702VMK) have the keyboards
backlight controlled by the keyboard firmware.

The firmware implements at least 3 different commands:
- Init command (to use when the system starts)
- Configuration command (to get keyboard status/information)
- Backlight level control (to change the level of the keyboard light)

With this patch we create the usual 'asus::kbd_backlight' led class
entry to control the keyboard backlight.

The error handling in sony_input_configured is a little tricky. It
is not easy to add other goto's as not all codepaths have logic
for adding this attribute. Luckily we are setting the value for the

b8f0970d2c HID: sony: Improve navigation controller axis/button mapping
The navigation controller is a DS3 (sixaxis) with fewer physical
axes and buttons. It utilizes the same HID report as the DS3 and
thus reports axes/buttons which aren't physically present.
Currently many non-existing buttons and axes are reported, which
we are now removing.

For the axes/buttons which do exist, we make the axis/button mapping
similar to the DS3.

5b036ea18e HID: logitech-hidpp: battery: provide CAPACITY_LEVEL
CAPACITY LEVEL allows to forward rough information on the battery mileage.
HID++ 2.0 devices will either report percentage or levels, so better
forwarding this information to the user space.

The M325 supports only 2 levels: 'Full' and 'Critical'. With mileage,
it will report either 90% or 5%, which might confuse users. With this
change the battery will either report "Full" or "Critical".

Unifying devices are different from others because they can probed
while not connected. So we need to talk to the receiver to get some

Instead of having conditionals while attempting to read the device name

Store the retrieved serial in hdev->uniq.
